Public masturbation is becoming a bigger problem on English underground rail lines and even buses. So I don't know for certain if this is real, but unfortunately the problem is so widespread, it probably is.

As much time as I spend on public transit when I go on vacation, I guess I'm lucky that I've never seen any of this myself (not even in NYC). Worst I usually get is mostly-harmless drunks, or panhandlers who won't leave the passengers alone. Or, worst of all, the Lex Ave line at rush hour.
